Title: Radio broadcast communications systems
Inventor: STEVENS JOHN K
IPC: H04L5/14
Filed: 1987-09-18
Granted: 1990-12-11
Abstract: ABSTRACT OF THE DISCLOSURE          The invention comprises a low power broadcast system that is applicable especially to the so-called "electronic shelf" for retail stores, wherein the shelf edge carries price displaying modules that can be addressed and controlled from a central computer operated station.  The system also permits the modules to broadcast back to the central station to confirm safe receipt of data and to give information as to stock levels, etc.  A broadcast system avoids the need for wiring so that location changes are facilitated.  To overcome the extremely noisy environment and to conserve power consumption, and hence battery life, the system employs a low frequency (132 kHz) reference carrier transmitted by the base station in discrete segmented packages, each of which frames a base data word transmitted by the base station and a corresponding module data word transmitted by the module a fixed period after the end of the base word; the base receiver then has precise time information for receipt of the module word and can "look" for it among the noise.  The carrier received by the module is divided and the lower frequency used to demodulate the information-carrying transmission from the base station of the same frequency, avoiding the need for a phase locked loop detector; this lower frequency is also used for the module transmission. The module employs an air-cored loop antenna coil for the lower frequency and a ferrite-cored loop antenna for the higher reference frequency, while the store antenna is segmented for selection of the group of modules to be addressed; the antenna contacts the metal shelving to provide electromagnetic coupling thereto.  Each module contains a microprocessor which controls the operation.  Each module has "concealed" buttons which can be enabled and used to insert data to be transmitted therefrom.  A charging circuit can be used as the power source employing the received RF carrier energy.

Abstract: MACHINE FOR FORMING CYLINDRICAL BALES OF CROP         Abstract of the Disclosure A baling machine for forming large cylindrical bales of hay has a variable volume baling chamber defined by moving belts with a crop inlet on the underside of the machine.  When a bale has been completed it is wrapped with surface wrapping material stored in a holder on the back of the baler.  The wrapping material is advanced by feed rolls through a cutting mechanism below the holder, and is thus guided by a plate extending along the underside of a run of the belts to the baling chamber.  In order to avoid wasting wrap, a cutter is triggered by a peg carried by a metering wheel movable between an adjustable "home" position against an abutment or stop to a trigger position in which it engages and lifts a release lever to release the cutter, and this distance is a measure of the length of wrap material required for the completed bale.  In respective embodiments, the metering wheel is in the form of a friction wheel, a worm wheel and a ratchet wheel with all wheels being selectively driven by one of the feed rolls.
